verbatim

\begin{verbatim}
text
\end{verbatim}

or

\begin{verbatim*}
text
\end{verbatim*}

The verbatim environment is a paragraph-making environment
that gets
LaTeX to print exactly what you type in. It turns LaTeX into a
typewriter with carriage returns and blanks having the same effect
that they would on a typewriter. The output looks exactly as it
looks in the input file.

The difference between verbatim and verbatim*
is that the latter prints spaces as "visual" spaces, i.e.,
a short, squat "u".

The only text which cannot be placed in the verbatim
environment is the 14-character sequence "\end{verbatim}".

The verbatim environment may not be used
in the argument of another command. However, it can be
placed inside a minipage environment which
allows you to manipulate it's placement.
